[shell72]

have a relative that due to medical issues has decided to back out of a real estate deal after sending over loan committment to agent. Other than losing the earnest money deposit, what other financial implications will they face?

[Mr. Knowitall]

This is your relative, or this is you? If it's your relative, have your relative come here and post some details.
